The solution to printer nozzle blockage

1. Immersion method

Scope of application: light obstruction.

Necessary tools: 95% alcohol, a clean cup, and a metal container with smooth bottom.

Working principle: dissolve the ink particles one by one with a medium-strength organic solvent. Note that 95% concentration of organic solvent alcohol must be used, otherwise it will be counterproductive.

Solution: first find a metal container with a smooth bottom and add a little 95% concentration of organic solvent alcohol into the container. The alcohol is limited to just covering the stainless steel edge of the nozzle (be careful not to let the PCB board come into contact with alcohol). The soaking time generally ranges from 2 hours to 4 days. The utility model has the advantages of a good cleaning effect and not easy to cause physical damage to the nozzle; The disadvantage is that it takes a long time to solve the urgent needs of users.

2. Distilled water cleaning method

Scope of application: serious obstruction.

Necessary tools: a decoded empty ink cartridge, a disposable syringe, and a bottle of medical distilled water (which can also be replaced by purified water).

Working principle: the working principle is similar to that of the pressure cleaning method.

Solution: first prepare a decoded empty ink cartridge, a disposable syringe, and a bottle of medical distilled water, use the pressure generated by the siphoning effect of the syringe, suck the syringe into the distilled water, inject it into the ink cartridge through the vent hole of the ink cartridge, and then suck out the injected distilled water with the syringe after a while, to clean the remaining ink in the ink cartridge repeatedly.

3. Pressure cleaning method

Scope of application: serious obstruction.

Necessary tools: 95% alcohol, a clean cup, a disposable syringe, and a disposable infusion set.

Working principle: use the pressure generated by the siphon action of the syringe to inject alcohol, an organic solvent, into the print head, to clean the dry ink head.

Solution: use the plastic tube or needle part of a disposable infusion set to make the interface between the syringe and the ink supply port of the print head (the joint part must be tight). After the interface is made, place the print head in the organic solvent alcohol with a concentration of 95%, and inhale the alcohol through the print head (note that it can only be inhaled) into the syringe needle tube several times. The utility model has the advantage of a good cleaning effect. Generally, the print head with a heavy blockage can be cleaned by this method. It is worth noting that when inhaling alcohol, the force should be uniform and consistent, which generally will not cause physical damage. However, when making the interface, it needs to be made manually according to the actual situation. Therefore, it needs the cooperation of professional maintenance technicians and a certain hands-on ability to repair. They made tools that can ensure long-term use.

4. Ultrasonic instrument cleaning method

Scope of application: the most serious obstruction.

Working principle: use the ultrasonic cleaning machine to produce strong ultrasonic waves, make the water molecules vibrate violently, and dissolve the small dry ink particles in water after shaking, to achieve the purpose of cleaning.

Solution: gently put the universal printer nozzle into the cleaning machine and add purified water or special print head cleaning solution. The purified water or special print head cleaning solution is limited to just covering the stainless steel edge of the print head (pay attention not to let the PCB board come into contact with purified water or special cleaning solution). It can be cleaned quickly after starting up for 10 to 15 hours. Its advantage is that the cleaning effect is very ideal, the print head blocked for many years can be cleaned, and the operation is also very simple; The disadvantage is that the maintenance cost is high and the price is expensive. Generally, ultrasonic cleaning machines can be found in hospitals, glasses stores, or mobile phone special maintenance points, and some places are free, and ultrasonic humidifiers can also be modified. It is worth noting that the use of cleaning fluid must use purified water or special print head cleaning fluid. The cleaning fluid of hospitals, glasses stores, or mobile phone special maintenance points cannot be used, because the cleaning fluid of glasses stores generally contains more impurities, and the cleaning fluid of hospitals and mobile phone special maintenance points is generally a strong organic solvent. Frequent use will cause fatal damage to the inkjet print head that is difficult to repair.
